The purpose of this research is to develop an earthquake resistance system for high-rise reinforced concrete buildings. As a result of preliminary tests, it was found that the improvement of deformation capacity for side columns subjected to high alternating axial force was necessary. Three types of test structures, frame, frame with shear wall and outrigger type frame, with improved side columns were tested. Observed crack patterns and hysteresis loops of three test structures are described.Envelope curves of hysteresis loops were simulated well by a proposed simplified analytical method. It was found that the three test structures with the improved side columns had superior deformation capacities against major earthquauke. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
